I'm working on a quick little plug-in with the Illustrator CS3 SDK and am having some troubles inserting a single entry into the hierarchy list.  I have confirmed that my suites file is correctly calling in the ADMHierarchyListSuite5 class and am able to do everything I try to do in the following code except for add a new entry.

ASErr NewDialog::Init() {

    ASErr rslt;

    if(rslt = BaseADMDialog::Init()) {

        return(rslt);

    }

    this->SetThisPointer(this);

    IADMItem itmBtnCreate = this->GetItem(kNew_BtnCreateIndex);

    itmBtnCreate.SetTipString(kNew_BtnCreateTips);

    itmBtnCreate.SetNotifyProc(this->CreateButtonNotifyProc);

    IADMItem itmTboxName = this->GetItem(kNew_TboxNameIndex);

    itmTboxName.SetTextW(mUniSetText.as_ASUnicode().c_str());

    IADMItem itmListLayer = this->GetItem(kNew_ListLayerIndex);

    itmListLayer.SetItemStyle(kADMMultiSelectListBoxStyle | kADMDividedListBoxStyle);

    IADMList lstLayer = itmListLayer.GetList();

    lstLayer.SetEntryHeight(kNew_ListLayer_LineHeight);

    IADMRect rctList(2, 0, 206, kNew_ListLayer_LineHeight);

    lstLayer.SetEntryTextRect(rctList);

    long cntList;

    sAILayer->CountLayers(&cntList);

    if(cntList <= 0) {

        return(kNoErr);

    }

    IADMEntry entryLayer;

    ai::UnicodeString UniBuf;

    AILayerHandle tempHandle = NULL;

    AIBoolean visible;

    sAILayer->GetFirstLayer(&tempHandle);

    sAILayer->GetLayerTitle(tempHandle, UniBuf);

    sAILayer->GetLayerVisible(tempHandle, &visible);

    if(entryLayer = lstLayer.IndexEntry(-1)) {

        exit(670);

    } else {

        exit(671);

    }

    entryLayer.SetText("entryLayer");

    return(kNoErr);

}

I set up a quick test with the above if else statement to pinpoint that that is where the problem originates as it always exits on signal 671.  I can't seem to figure out why it fails though.  Is there something that I might be forgetting or is there some way for me to figure out the details as to why it's quitting?  I'm building this in Visual Studio 2008.

Thanks in advance
